Actually I was able to reverse calculate the head volume from known values of bore, stroke, compression ratio, etc...

Then took this with the known dome volume (from Andial) and was able to approximate the change in compression ration to be about .05-.1 per .1mm in height difference...

ENd result was what was important, that the small differences in my deck height from piston to piston (due to factory allowed variance in the crank) are not significant enough to affect compression ratio.

I am not able to adjust at all with differing rod lengths since my rods were re-sized and all within .025mm of each other...
